I did enjoy it even though it felt as if Johnny Ball should have been presenting it.

Yes, it was fairly elementary stuff but it did highlight the interesting fact that even now we're still using steam to power our generators and still shovelling hundreds of tons of coal to do the job. There must be a more efficient way of generating electricity?

And talking of efficiency, how much electricity gets lost travelling down overhead power cables? Can't they insulate them more?
